+# About
+
+The communications project will deliver a balloon payload that allows
+receipt of [telemetry](https://en.wikipedia.org/wiki/Telemetry) and
+other payload data as well allow command of the balloon systems as
+needed. Communications are commonly delivered over [Amateur
+Radio](https://en.wikipedia.org/wiki/Amateur_radio) frequencies by
+licensed operators. Networks like
+[APRS](https://en.wikipedia.org/wiki/Automatic_Packet_Reporting_System)
+are favored for some balloon-related communication.
+
+These team members will also be responsible for ensuring one or more
+suitable ground stations are in place to reliably receive data from the
+communications systems. This team is encouraged to partner with the
+[HacDC Amateur Radio club](http://www.w3hac.org) and [other amateur
+radio organizations](http://www.arrl.org/find-a-club) and enthusiasts.
+This team will also facilitate logistical communications primarily for
+the launch and recovery teams.

+- Derk
+- [Ethan Waldo](User:Ewaldo "wikilink") (licensed for Amateur Radio)
+- Martin (licensed for Amateur Radio)
+- Nancy Wolfson
+
+# Possible Balloon Communications
+
+- Primary VHF APRS tracker - sends regular APRS beacons with GPS and
+  limited telemetry - use national 144.390 MHz network
+- Secondary UHF APRS tracker - sends regular APRS beacons with GPS and
+  limited telemetry - use a frequency to be determined at the launch
+  site
+- 13 cm Broadband Downlink - send realtime video or broadband data
+- uhf/vhf cross-band repeater - allow hams to communicate long distance
+  with handy-talkies
+- 433 MHz ISM band low data rate telemetry
+
+# Possible Chase Team Communications
+
+- Cell phone WiFi for APRS.fi information
+- VHF and UHF APRS receiver, possibly tracking, text and digitpeating
+  for off-grid operations
+- Primary Voice - cell phone
+- Secondary Voice - VHF and UHF mobile radios in conjunction with
+  repeaters for off-grid operations operations
+
+# Possible Ground Station Communications
+
+- 13 cm broadband receiver/recorder with 90 cm dish
+- UHF/VHF receiver/recorder for SSTV
+- 433 MHz data receiver/recorder with yagi
+- Primary Voice - cell phone
+- Secondary Voice - VHF and UHF mobile radios in conjunction with
+  repeaters for off-grid operations operations
